Temp paint / primer to retard rust

[kizer]

I've been working on my rear frame with the bed off and I plan on moving up to the front so I can pull the front clip off and then the cab to finish the frame and look at suspension components. Now I know when I start pulling pieces off I'm going to open up sprayed paint because you can tell this thing has been resprayed after the original paint. Rust is going to show its UGLY face and since its going to be a bit cold outside I won't have all the tools and time to cut out and goto town. Oh did I mention I have hardly any bodywork skills.

Is there anything I can spray on the panels until I can address it? My plan is to take an inventory of what needs to be kept and what needs to be replaced/repaired while I take things apart. Im not looking for a magic rust cure paint, but simply something I can temp spray that would be removeable or able to cut out if need be.

I thought about whatever is bare just hitting it with some rattle can Black Rustolueum Paint then later when I start panel work I could grind, blast, whatever or am I wasting my efforts? I'm thinking depending on what needs what it would be a few months upto a year before I could cut/weld or if its just a bare surface really prime and paint.

Also with the front taken apart I want to start tinkering with the motor some and what better of an engine stand than the frame.
